An Approach to Determine the Weibull Parameters for Wind Energy Analysis: The Case of Galicia (Spain)

Carrillo, Camilo; Cidrás, José; Díaz-Dorado, Eloy; … - In: Energies 7 (2014) 4, pp. 2676-2700

The Weibull probability density function (PDF) has mostly been used to fit wind speed distributions for wind energy applications. The goodness of fit of the results depends on the estimation method that was used and the wind type of the analyzed area. In this paper, a study on a particular area...
